Title: A process for the production of higher unsaturated aliphatic alcohols
IPC: C07C33/025
Filed: 1937-03-12
Abstract: Unsaturated fatty acids containing at least 8 carbon atoms are reduced to the corresponding unsaturated alcohols by treatment at elevated temperature and pressure with hydrogen in the presence of a catalyst containing copper and from 20--60 per cent of cadmium monoxide calculated on the weight of the copper, but no other catalytic metal, deposited on a carrier such as kieselguhr, asbestos or pumice.  Fatty acids specified are oleic, undecylenic, erucie, linoleic, and those from non-drying or drying oils such as olive, soya, cotton seed, rape seed, linseed, wood, train, sperm or whale oil.  They are mixed with about 5--20 per cent of the catalyst or, preferably, the reduction of the catalyst is effected after admixture with the acid at a hydrogen pressure of below 30, e.g. 10--20 atm., and at about 100--200 DEG  C.  The mixture is then further heated to at least 280 DEG  C., preferably at a pressure of 200 atm. or more produced by introducing more hydrogen.  Water vapour formed in the reduction step may be removed by circulating the hydrogen through drying apparatus or by venting it and introducing dry hydrogen.  The reaction autoclave, suitably of a steel alloy such as V4A steel, may be plated internally with a copper-cadmium layer, for example by effecting several reductions in it.  The products may be purified by treating with saponifying agents and distilling.  Examples describe the reduction of oleic acid with a catalyst made by treating a solution of copper sulphate and cadmium nitrate with sodium carbonate, mixing the precipitate with kieselguhr or animal or wood charcoal, washing, drying at 130 DEG  C., and then reducing in presence of the acid.ALSO:A catalyst for the hydrogenation of unsaturated fatty acids to alcohols contains copper and from 20--60 per cent of cadmium monoxide calculated on the weight of the copper, but no other catalytic metal, deposited on a carrier such as kieselguhr, asbestos or pumice.

Abstract: 453,167. Electric tests. SAWYER, E. R., 189, Liverpool Road, Islington, London. March 11, 1935, No. 7549. [Class 37] Apparatus for testing the emission of wireless receiving valves having three or more electrodes comprises a source S of low voltage of approximately 6 volts D.C. or 12 volts A.C., a milliameter M and a resistance R1, joined in series and connected between the cathode C and the grid G of the valve V to be tested, while a second resistance R2 is connected between the grid and the anode or other electrode of the valve in such a way that a positive or alternating current is applied to these electrodes with respect to the cathode. Under these circumstances, it is stated that the current reading obtained is approximately the same for all valves to be tested of which the emission is unimpaired, the changes in the voltage drop across the resistances serving to counterbalance any changes in the current which would otherwise arise on account of the different emissions of different valves. A further resistance R3 may be connected between the cathode C and filament F of an indirectly heated. valve, a switch being provided which when opened interrupts the connection between filament and cathode, and any reading recorded bv the ammeter M is then due to a fault in the valve. When the valve is provided with more than three electrodes, the cathode and grid are connected as above and the next electrode adjacent the grid is connected in the same way as the anode of the valve V, the other electrodes being left free.

Abstract: 1,263,243. Monitoring flames photoelectrically. NATIONAL RESEARCH DEVELOPMENT CORP. May 19, 1969 [Feb.17, 1968], No.7894/68. Heading G1A. A flame monitor comprises a photo-cell shielded by a filter designed to pass only a limited wavelength range so that flame radiation can be distinguished from other radiation. The filter is preferably cyan and the photo-cell controls the operation of a trigger circuit which operates an alarm or shut-down system. As shown, when photo-cell V1 is illuminated the voltage on trigger tube V2 rises until it conducts and operates relay contacts B1 to light neon indicator N3. If the flame goes out, tube V2 will extinguish when the supply voltage falls to zero and relay contact will changeover causing the alarm neon N4 to be lit and the external circuit connected at point A to be energized.
